FASTENER SLIDE.

Appli-cation filed February 29, 1928. Serial No. 257,973.

lVat-.erproot overshoes, o1E the well known types of arctics and galoshes, have been provided with straps, of the sainematerial as the uppers, on which are mounted fastening 5 members cooperating with complemental tastening members lined to the opposite side ot the shoe opening from that on which the straps are secured; and in some instances the fastening members on the straps are made in lo the nature of slides which may be adjusted on the straps in order to provide for securing a substantially tight closure oit' the opening. ln the instances ot such adjustable slide fastenings to me known, the slides have transversely slotted openings :tor the passage of the straps, and in all such instances the constructions aresuch as to cause the strap to bulge within the contines oli the slides in an unsightly and inconvenient manner. ln order to secure such slides in adj usted positions on the straps, the slides have been provided with a prong extending oit from the center bar in such way as to dig into the material ot the strap, These straps when made of material like that in the uppers of the slices, have the outside material folded over with its edges meeting in a center line, and where a single prong is used, it is located on the slides in a line with this joint and has a tendency to wear the strap at the point ot least resistance. When using the one-,pronged slides, those who assemble them kon the straps `must be careful to locate the prong in such position as to ensure the engagement of the prongY with the strap and resist the slipping of the slides from adjusted position.

The object ot the present invention is to provide a slide that will not cause the strap to bulge, and which has roomy slots for the easy passage of the strap in assembling and to avoid the bulging ot the stra-p, and having a plurality of prongs on bot-h edges of the center bar, located out of the line oi' the meeting edges ot the stra-p so as not to engage the strap in the line of said meeting edges, but on opposite sides thereof, and also to provide that the slide may be assembled on the slot regardless of the direction ot strain; or in other words, so that the prongs will engage the strap to hold the slide in adjusted position regardless of which way the slide may be assembled on the strap.

The invention consists of a fastener slide7 having a center bar located below the plane of the frame, and having roomy slots on oppo site sides, the center bar carrying the fastening element, which latter may be the head or stud or the socket member of a snap fastener; said center bar having on opposite sides of the fastening element upwardly extending prongs pointing in opposite directions toward opposite ends of the slide and serving to ei'igage the strap which ever way the slide may be placed upon the strap and thus to hold the slide in adjusted position, secure against the strains in use, as l will proceed now to eX- plain more fully and linally claim.

in the accompanyingdrawings illustrating i the invention, in the several figures of which like parts are. similarly designated, Figure l is a perspective view illustrating one embodinient of the invention and applied to a strap which is shown partly in tull and partly in dotted lines. Fig. 2 is a plan view ot' one side of the slide, and Fig. 3 a similar view of the reverse side. Fig. 4 is a side elevation showing the strap in dotted lines, these four ligures illustrating the invention as applied to a head or stud member of a snap fastener. Fig. 5 is a top plan view, and Fig. 6 a plan view ot the reverse side ot a slide embodying the socket member of a snap fastener, and Fig. is a section on line 7 7 ot Fig. 5.

Une method of forming waterproof straps for arctics and galo-shes and similar overshoes, consists in folding over the material l upon an adhesive strip 2 and the parts adhered, and having thej edges of the part l meet substantially in the longitudinal center of a strap, as indicated at. Ot course, the invention is not limited to its use in connection with such a strap and said strap is shown for illustrative purposes. The strap is designed to receive a fastener slide, which may be adj ust-ed thereon so as to close the opening in the upper of the shoe to such an extentas .to make the shoe comfortable to the wearer.

The slide comprises the side trame elements d, between which is arranged the center bar 5, and this center bar is adapted to receive or be provided with a snap fastener element, such as the head or stud 6 which projects outwardly therefrom. The center bar is provided on opposite edges with the upstanding prongs 7 pointing in opposite directions and arranged out of line with the fastener element 6. The trame elements 4 are connected with the frame elements or end bars 8 by means of the aftermentioned offsets, so that the center bar 5 and end bars 8 are in sub-v stantially parallel horizontal planes and are spaced apart suliic-iently to permit the passage between them of the strap Without niaterially bulging the strap at. the point of connection, but on the contrary permitting the strap to lie substantially fiat, as indicated in Figs. l and 4t. its shovvn in Figs. l and il, the prongs 7 enter the strap and prevent the slipping of the slide on the strap after it has been once fixed in adjusted position.

The provision of the oppositely inclined pairs of prongs admits of the application of the slide to the strap either end on, as it is apparent that the prongs on either side of the center bar will resist the strains of use and prevent slipping of the slide in one direction.

Between the center bar and the end bars 8, are slots 9, of considerable height and width so as to provide for the ready application of the slide to the strap. is Will be seen by reference to Figs. l, 2 and 3, the slots extend beyond the ends of the center bar and thus cooperate With the spacing apart of the center bar -and end bars to provide roomy slots hereinbefore referred to. rllie center bar and the end bars are connected at the sides of the slide by means of the oqsets lO.

lt Will be observed that the center bar is substantially fiat, so as to lie as close to the strap as possible and thus avoid the bulging of the strap.

As shown in Figs. 5, 6 and 7, the shape of the slide may be varied and still retain some r all of the features previously described, but with the center bar having a resilient or non-resilient socket member il applied to orformed therewith. With this construction there is no need of spacing the end bars l2 from t-he center bars 13 as far as shoivn in the slide of Figs. l to Ll. Moreover, the frame, composed of the end bars la and side bars la, may have a substantially rectangular outline With the parts concaved as shown at 15 in Figs. 6 and 'Y'. rllie center bar 13 as in the case of the slide shown in Figs. l to ll, has the upst-anding pairs of prongs i6 arranged on opposite sides of the snap fastener element 11 and projecting from the center bar in opposite directions so as to iinpale the slide on the strap Whichever Way the slide may be applied to the strap. 17 are the slots for the passage of the strap.

tenesse Where, as in prior constructions, asingle cent `al prong has been used, on the center bar of the slide for use on the straps of arctics, galoshes and other overshoes, the central arrangement brings the prong substantially into the line of Weakness of the strap, indicated at 3, and not only tends to open the strap covering, but also prevents an eiective hold on the strap. Moreover, with one or any other number of prongs located on one side only or the center bar, the same diiliculty occurs of requiring the workmen to place the slide on the strap in the one and only direction in Which the prongs become effective.

'llie use ofprongs on both sides-of the center bar assists the operator in mounting the slides onv the strap, and it is not necessary for him to'loolr at each slide to make sure that it is mounted with the prongs in the proper direction. lt is also to be noted that the use of two prongs facing in the direction of the tendency of the slot to slip, dig into the material of the strap at tivo points and thereby effect abetter holding quality than one prong.

Variations in the details of construction are permissible Within the principle ofthe invention and the scope of the claims folH lowing.

lhat l claim is l. A fastener slide, having side and end bars, a center bar spaced from the end bars to provide roomy slot-s for the substantially flat passage of a strap on which the slide is mounted, a fastener element on the center bar, and a plu 'ality of upstanding prongs projecting from opposite sides of the center bar and in opposite directions and toward the opposite ends of the slide, so as to engage the strap Whichever Way the slide may be applied to the strap.

2. A fastener slide, having side and end bars, substantially latcenterbar having a fastener element, the side and end bars being spaced apart and connectedby offsets, there being roomy slots between the center bar and the end bars and the offsets, and upstanding prongs on both edges of the center bar and on opposite sides of the fastener' element and inc-lined toivard the opposite ends of the slide.

In testimony whereof have hereunto set my hand this 28th day of February, A. D. 1928.
